我创建了一个 Azure DevOps 任务组来在 Azure(Azure 容器实例)上创建一个 selenium 容器,如下所示:
脚本:
ipAddress="$(az container create \
-g $(resourceGroup) \
--name temp-$(ContainerName) \
--image myregistry.azurecr.io/selenium/standalone-chrome \
--cpu 2 \
--memory 4 \
--os-type Linux \
--ports 4444 \
--vnet $(VNet)
--subnet $(Subnet)
--registry-username $(registryUsername) \
--registry-password $(registryPassword) \
--environment-variables \
NODE_MAX_SESSION=10 \
Browser=$(Browser) \
--query 'ipAddress.ip' -o tsv)"
echo "##vso[task.setvariable variable=$(SeleniumHubVariable);]http://$ipAddress:4444/wd/hub/"
在 Linux 构建代理上运行时,此任务成功执行。
当我尝试在 Windows 构建代理上运行它时,任务不会失败,但不会创建容器。任务的输出如下:

我错过了什么?如何使其同时适用于 Windows 和 Linux?
最佳答案
我现在可以使用 2 个任务使其与 Windows 代理一起使用。
任务 1 (Azure CLI) - 创建容器实例并将命令(IP 地址)输出到文件
脚本:
az container create ^
-g $(resourceGroup) ^
--name temp-$(ContainerName) ^
--image myregistry.azurecr.io/selenium/standalone-chrome ^
--cpu 2 ^
--memory 4 ^
--os-type Linux ^
--ports 4444 ^
--vnet $(VNet)
--subnet $(Subnet)
--registry-username $(registryUsername) ^
--registry-password $(registryPassword) ^
--environment-variables ^
NODE_MAX_SESSION=10 ^
Browser=$(Browser) ^
--query "ipAddress.ip" -o tsv>tmpFile-$(ContainerName).txt
一些注意事项:
\
字符已替换为^
- 单引号在 Linux 上工作正常(
--query 'ipAddress.ip'
),但在 Windows 上我必须使用双引号(--query "ipAddress.ip"
) >)
任务 2 (Powershell) - 从文件中读取 IP 地址并设置环境变量
$ipAddress = [IO.File]::ReadAllText("tmpFile-$(ContainerName).txt")
Write-Host "Selenium hub URL is http://$($ipAddress.Trim()):4444/wd/hub/"
Write-Host "##vso[task.setvariable variable=$(SeleniumHubVariable);]http://$($ipAddress.Trim()):4444/wd/hub/"
为任务设置自定义条件
不幸的是,我必须为每个操作系统(Windows 或 Linux)创建不同版本的任务:
要根据构建代理的操作系统运行这些任务,您可以设置自定义条件:
因此,要在 Windows 构建代理上运行任务,您可以设置此自定义条件:
and(succeeded(), eq(variables['Agent.OS'], 'Windows_NT'))
要在 Linux 构建代理上运行它:
and(succeeded(), eq(variables['Agent.OS'], 'Linux'))
PS:Agent.OS
可以在构建代理功能上找到
关于Azure CLI 任务不适用于 Windows 构建代理,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/56750104/
